Extractive Metallurgy of Nickel, Cobalt and Platinum Group ...

Controlled levels of nickel, iron, and coal in the calcine ensure efficient production of ferronickel with a constant composition during smelting. Ninety percent of smelted ferronickel is used in making stainless steel and other ferrous alloys. The balance is smelted to sulphide matte for refining to nickel metal and other nickel products.

Nickel Flash Smelting :: Total Materia Article

Using nickel flash smelting technology it is possible to process sulfide nickel concentrate and produce nickel matte and slag in a relatively efficient process. Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte.

Histone Methylation in Nickel-Smelting Industrial Workers

Introduction. Nickel is one of the most abundant trace metals on Earth, and is widely distributed in the general environment. It is used in various occupational settings, including in mining, smelting, and refining and in the alloy production and welding industries[].Workers employed in these industries are chronically exposed to nickel and related compounds, and non-occupational exposure is ...

NICKEL in the EUROPEAN UNION - OMA

Nickel-containing ore is usually smelted to produce a raw material for the steel industry ("ferronickel") or for subsequent refining into nickel metal or nickel containing chemicals. Nickel is refined into high purity nickel, notably in Finland, France, Norway and the United Kingdom. Chemicals Smelting Mining Refining new-Caledonia

Environmental Guidelines for Nickel Smelting and Refining

436 Nickel Smelting and Refining cathodes is the most common technology used for nickel refining. Electrowinning, where nickel is removed form solution in cells equipped with inert anodes is the more common refining process used for nickel. Chloride electrolytes are used although sulfuric acid solutions are used more often. Waste Characteristics
